Qing Wang, Ning Liu, Yuan-Shu Ni, Jia-Mei Yang, Lin Ma, Xiao-Bing Lan, Jing Wu, Jian-Guo Niu, Jian-Qiang Yu,

Ischemic stroke has a high lethality rate worldwide, and novel treatments are limited. Calcium overload is considered to be one of the mechanisms of cerebral ischemia. Transient receptor potential melastatin 2 (TRPM2) is a reactive oxygen species (ROS)-sensitive calcium channel. Cerebral ischemia-induced TRPM2 activation triggers abnormal intracellular Ca<sup>2+</sup> accumulation and ... Read more >>
